'ZDNET Recommends': What exactly does it mean?

ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.

When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.

ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services.

While the iOS 18 general release is still months away, users can download a public beta as soon as next month and the iOS 18 developer beta today. Before you download a beta version of an operating system, you should have some housekeeping items in mind:

  1. Back up your device and personal information
  2. Try not to download the developer software, likely to have bugs and glitches, on your everyday iPhone
  3. You should go into the experience with the goal of testing new features and sharing feedback for the betterment of iOS
